Performance enhancement for CRM entity page loads

With this release of Unified Service Desk 3.2, you can experience enhanced performance of CRM entity page loading in Unified Service Desk with the Internet Explorer Pooling feature.

Unified Service Desk always maintains a pool of Internet Explorer instances for hosted controls to use. Opening a hosted control using a pooled Internet Explorer instance enhances the performance of the Unified Service Desk.


  • The Internet Explorer pooling feature supports only CRM entity pages hosted in CRM page hosted control.
  • When you enable the pooling feature and open a CRM page hosted control, you can see in Task Manager that Unified Service Desk creates a number of Internet Explorer process instances for hosted controls to use.
  • The performance of the Internet Explorer pooling feature is dependent on the resources available on the client computer.
